Implement one small habit this week
Research shows that single-habit adoption is 2–3× more likely to stick than multi-habit changes. Start with whatever your lowest-scoring area revealed.
How We Approach Growth Research
Every guide and tool in the Growth section is built on a consistent research framework. We prioritise systematic reviews and meta-analyses over single studies, flag when evidence is emerging or mixed, and update content when the literature meaningfully shifts.
Primary sources first
We cite original peer-reviewed research. When we reference a claim, we link to the specific paper, not to a secondary commentary.
Evidence grading
Claims are graded by evidence strength: Strong (multiple RCTs/meta-analyses), Moderate (cohort studies), Emerging (early-stage research).
Expert review
Content in this pillar is reviewed by practitioners with relevant clinical experience before publication.
Regular updates
Science evolves. We review and update our most-read content when new evidence meaningfully changes the picture.
Evidence Quality in Growth
Scores represent our editorial assessment of evidence quality and replication rate in key topic areas.
Common Questions
The "21 days" myth has no scientific basis. A 2010 UCL study found habit formation takes 18–254 days, with a median of 66 days. Simpler behaviours in familiar contexts form faster.
Decades of research suggest that consistent deliberate practice, self-regulation, and persistence are stronger predictors of long-term achievement than IQ above a threshold of approximately 120.
